a day that will forever live in infamy, when america was attacked by forces of evil. joining me to remember that trangic day, september 11, 2001, america's mayor, rudy guiliani. this is not political, but your leadership during that time was amazing. i remember moments where you said, hey, we have to keep living, when you went on letterman. when he said to you, can we laugh again? those were important moments for the country. sent a strong message. >> i had tremendous support. tonight, after i leave you, vidinner with a hundred people who were with me and helped me, got me through t. we get together every september 11 and just remember people we lost. i thank them for all the support they gave me. i wouldn't have got through it by myself. when i was knighted by keen elizabeth, i said to her that i stood on the shoulders of gand r them. it was really true. hitremendous people.
